Abstract

Det blir beskrevet et florstoff av elektretfibre med forbedret ladningsstabilitet, bestående av råstoff som overveiende inneholder et fiberdannende polymerisat eller polykondensat og 0,01 til 30 vekt-* (fortrinnsvis 0,01 til 10, spesielt 0,1 til 5 vekt-*) av råstoffets totalvekt av organiske eller metallorganiske ladnings-lagringsmiddel, som er kjennetegnet ved at florstoffet inneholder minst to typer elektretfibre som består av forskjellige råstoffer som skiller seg fra hverandre, at de inneholder forskjellige fiberdannende polymerisa-ter eller polykondensater og eventuelt også forskjellige ladningslagringsmidler.Det blir dessuten beskrevet en fremgangsmåte for fremstilling av disse florstoffene og deres anvendelse 1 fremstillingen av høyvirksomme støvfiltere og støvtørkekluter.
